LATCH.

SPECIFICATION forming part of Letters Patent No. 417,970, dated December24, 1889.

Application filed July 2'7, 1889. Serial No. 318,848. (No model.) i

To all whom it may concern.-

Be it known that I, EDWARD F. BARROWS, a citizen of the UnitedStates,and a resident of Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements inFastenings for Refrigerator and other Doors; and I do declare thefollowing to be a full,olear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to letters of reference marked thereon, which. form a part of thisspecification.

Figure 1 of the drawings is a representation of a perspective View ofthe invention applied. Fig. 2 is an interior View showing thecam-fastener. Fig. 3is an open view of the lock-case and its mechanism.Figs. 4, 5, and 6 are details.

This invention relates toadjustable fastenings and locking devices forthe same for refrigerator and other doors; and it consists in the novelconstruction and combination of parts, as hereinafter described, andpointed out in the claims.

The object of the invention is to construct a fastening especiallyadapted for refrigerator-doors, whereby the said doors shall always hebrought to close fit with the doorframe if at any time there should bewarping or irregularity of the parts; also, to provide a locking devicewhereby the fastening may be held in position and serve the purpose of alock.

In the accompanying drawings, the letter A designates the door of arefrigerator, and B the door-frame.

G indicates the lock-case on the front of the door, having circularprojection a registering with a similar perforation in the door for theintroduction of a spindle D. The said spindle is rectangular in form,except the end, which is threaded, and is provided with handle E, havingshoulder b, which bears against the face of the lock and projectsthrough the door on the inside to receive a cam-like plate or fastenerF.This fasteneris eccentrically attached to the spindle at right anglesthereto, and is adjustably secured by anut c on the threaded end of thespindle.

The thickness of the fastener increases from the point of attachment tothe spindletoward its periphery to form an inclined or beveledbearing-surface d for engaging the face of the plate G on the inside ofthe doorframe when the spindle is turned to fasten the door. The objectof the beveled face of the cam is to draw the door gradually in closerelative position to the frame, which is effected as the broad portionof the fastener encroaches against the bearing-plate G while the spindleis being turned. The distance traveled by the fastener on the plate G islimited'by the engagement of the rear lug d of the fastener with thestop-lug e of the inner door-plate I. The same stop-lug preventscomplete backward revolution of the fastener by engaging the oppositeside when the action of the spindle is reversed to openthe door.

When it is desired to secure the fastener in locked position, a lockingdevice operated by a removable key is used to prevent turning of thespindle. This device consists of the slotted slide A, operating in thelock-case C at right angles to the spindle D in suitable guideways, andhaving a rectangular open slot or notch to engage the rectangularspindle as it passes through the case. This slide is held in position byone or more rocking tumblers, which are engaged and disengaged bythekey, and in consequence of the locking mechanism being concealed by thecase 0 the spindle cannot be released, being once in engagement with thenotch of the slide, without the use of a key.

When the door-fastener is to be used without a locking device, thelock-case is dispensed with and a simple plate or'escutcheonsubstituted.

What I claim as new, and desire to secure by Letters Patent, is-

1. The door-fastener consisting of the spindle havingthe eccentricprovided with an inclined face or edge bearing against the plate on thedoor-casing, and with a lug engaging a stop-lug 011 the door-plate asthe eccentric eifects the locking of the door, substantially as setforth.

2. In adoor-fastener, the combination, with the rectangular spindle, ofthe locking-plate adapted toengage said spindle as it is aetu- Intestimony whereof I affix my signature in ated by the key, and arrangedin connection presence of two witnesses.
